标签:android   浮点   腾旭手机管家火箭   windowmananger   windowmananger.layou   

好久没有写过博客了,前段时间一个项目中用到了浮点(漂浮在窗体上),于是突发灵感发现可以实现类似于腾讯手机管家火箭升空效果

    实现步骤:1:新建一个类 名为RocketView(用来显示浮点,当手指拖动浮点变成火箭图标)

                        2:新建一个类 名LaunchView(火箭发射台,当手指拖动RocketView浮点到指定位置释放手指后 火箭深空)

                        3:在activity中调用RocketView的显示浮点方法进行演示

                        4:总结

package com.masa.rocketlaunch;

import java.text.Format;

import android.content.Context;
import android.graphics.PixelFormat;
import android.os.Handler;
import android.util.AttributeSet;
import android.util.Log;
import android.view.Gravity;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;
import android.view.WindowManager.LayoutParams;
import android.widget.ImageView;
import android.widget.ImageView.ScaleType;
import android.widget.RelativeLayout;

/**

 * 类说明   火箭发射台
 */
public class LaunchView extends RelativeLayout{

	
	private static final String TAG = LaunchView.class.getSimpleName();
	private WindowManager wm;
	private WindowManager.LayoutParams wlp;
	
	private Context ctx;
	
	public int x;//发射台的x坐标
	public int y;//发射台的y坐标
	public int r;//待中心点的半径
	
	
	private Handler handler=new Handler(){
		public void handleMessage(android.os.Message msg) {
		    
		 	
		};
	};
	public ImageView ivfire;
	
	
	public LaunchView(Context context) {
		this(context, null);
	}
	
	public LaunchView(Context context, AttributeSet attrs) {
		this(context, attrs, 0);
	}
	
	
	public LaunchView(Context context, AttributeSet attrs, int defStyleAttr) {
		super(context, attrs, defStyleAttr);
		ctx=context;
		
		wm=(WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
		wlp=new WindowManager.LayoutParams();
		
		
		
		ViewGroup.LayoutParams vlp=new ViewGroup.LayoutParams(-1,DimensionUtil.dip2px(context, 108));
		this.setLayoutParams(vlp);
		this.setBackgroundResource(R.drawable.rocket_base);
		
		ivfire = new ImageView(context);
		ivfire.setScaleType(ScaleType.FIT_XY);
		setImageFire();
		RelativeLayout.LayoutParams rlp=new RelativeLayout.LayoutParams((int) (DimensionUtil.getWidth(context)/4.5)*2,(int) (DimensionUtil.getWidth(context)/4.5));
		rlp.addRule(CENTER_IN_PARENT);
		this.addView(ivfire, rlp);
		
		r=(int) (DimensionUtil.getWidth(context)/4.5);
		x=DimensionUtil.getWidth(context)/2;
		y=DimensionUtil.getHeight(context)-r;
		Log.i(TAG, "x:"+x+"   y:"+y+"   r:"+r);
	}
	
	public void setImageFire( ){
		ivfire.setBackgroundResource(R.drawable.rocket_fire1);
	}
	
	public void isShowFire(boolean isshow){
		ivfire.setVisibility(isshow?View.VISIBLE:View.GONE);
	}
	
	public void addToWindow(){
		wlp.flags=WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL|WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
		wlp.type=WindowManager.LayoutParams.TYPE_PHONE;
		wlp.gravity=Gravity.LEFT|Gravity.TOP;
		wlp.format=PixelFormat.RGBA_8888;
		
		wlp.width=this.getLayoutParams().width;
		wlp.height=this.getLayoutParams().height;
		
		wlp.x=0;
		wlp.y=DimensionUtil.getHeight(ctx);
		wm.addView(this,wlp);
	}
	
	
	public void removeView(){
		wm.removeView(this);
	}
}


3:在activity中调用RocketView的显示浮点方法进行演示


	    RocketView rocketView=new RocketView(this.getApplicationContext());
	    rocketView.setLaunchView(new LaunchView(this.getApplicationContext()));
	    rocketView.addToWindow();

4:总结

         浮点的实现主要使用到android api的WindowManager,以及对WIndowManager.LayoutParams的一些参数的熟悉。
         
作者能力有限,特别是设计模式方面 不是很懂,希望高手多多指点
